And sometimes they disappear. Once they set foot on the Combine, they are submitting themselves, temporarily, to Creterakian law. So if the modifications are particularly grevious, the Quyth Warrior in question may just cease to be. It’s not like it’s a secret, so anyone with mods who enters the Combine is taking their chances.

So, the Quyth Concordia was never conquered by the Creterakians. However, Quyth Warriors still have to go to the Combine to get cleared for upper tier ball.

So what happens when a Quyth Warrior goes to the Combine, and is found to have bio or cybernetic mods? Do the Creterakians still get to imprison or kill them? If that’s the case then Quyth Warriors must have to sign some contract that releases their rights as a Quyth Citizen or something, and lets the Creterakians enforce their rules without causing an intergalactic military episode.
